Patent JP-S6292304-A (JP)
Title: Electric resistor and its manufacture
Inventor: YOSHIDA KAZUO
IPC: H01F7/06
Filed: 1985-10-17
Abstract: PURPOSE:To reduce the change of resistance with respect to temperature, by constituting a laminated layer structure composed of at least two layers, the one being a first layer wherein conductive particles are diffused in high-molecule binder, the other being a second layer composed by amorphous carbon. CONSTITUTION:As for a first layer, electrically conductive particles 1 are dispersed in electrically insulative high-molecules as the binder 2. The conductive particles 1 come into contact mutually, so that the first layer is made conductive as a whole. A second layer is composed of amorphous carbon 3 which means the carbon material having no distinct crystal structure. The second layer may be of a uniform constitution composed of amorphous carbon only, or a matrix composed of amorphous carbon in which conductive particles are dispersed.

Title: Clipper circuit
Inventor: KAMIMURA TAKUZO
IPC: G05F3/04
Filed: 1984-11-02
Abstract: PURPOSE:To optionally and highly accurately set a clipping level from the outside, by setting a clipping voltage on the basis of a set reference voltage and clipping an input signal by outputting the clipping voltage through a buffer circuit. CONSTITUTION:When a control voltage VC is applied across controlling input terminals 6 and 8, a reference voltage Vref is formed in such a way that a differential output corresponding to the voltage VC is applied to the base of a transistor (Tr)9 and an electric current corresponding to the voltage VC is made to flow to the Tr9. The voltage Vref is applied across a differential amplifier 16 and its output voltage V0 becomes the mid-point level of a clipping level. When a constant current is made to flow from a constant-current source 20 to another constant-current source 22 through resistances 24 and 26, clipping voltages +VD and -VD are formed at each terminal of the resistances 24 and 26. The voltages + or -VD are generated at emitters of Trs36 and 38 through differ ential amplifiers 32 and 34 and Trs36 and 38 and a clipping output VOCL is given in the form of VOCL=V0+ or -VD. Therefore, the clipping output VOCL is generated at an output terminal 40 when an inputvoltage VIN is given to an input terminal 44.

Title: Power unit
Inventor: TAKAHASHI TSUNEHIDE
IPC: G03G15/00
Filed: 1987-09-18
Abstract: PURPOSE:To reduce noises by synchronizing the clock of a computer which controls a system with the clock of a microcomputer which control a power source or using the same clock as the both. CONSTITUTION:Processing in the microcomputer 4b is performed with a signal from an oscillator 4a. A high-voltage power source unit 6 receives serial data from a copying process control unit 4 and changes the switching conditions of a converter 6a according to the data to turn on or off its output or varies the output value. The output of the converter 6a is fed back to the input of the microcomputer 6b in the high-voltage power source unit 6 and controlled to a target value. This microcomputer 6b operates by using a signal from the oscillator 4a in the copying process control unit 4 as a clock. Consequently, higher harmonics due to mutual interference are not generated and noises are reduced.

Title: Alkaline battery and negative electrode active material therefor
Inventor: NAKAMURA KIYONOBU
IPC: H01M4/62
Filed: 1988-09-20
Abstract: PURPOSE:To greatly suppress hydrogen gas generation and yet improve discharge performance by adding a particular amount of alkylbenzene sodium sulphonate to a negative electrode active material consisting of zinc alloy powder. CONSTITUTION:There are comprised zinc alloy powder, an electrolyte, and a negative electrode material 3 consisting of 100 pts.wt. of zinc alloy powder and 0.001-1.0 pts.wt. of alkylbenzene sodium sulphonate added to it. If the added amount of alkylbenzene sodium sulphonate is less than 0.001 pts.wt., the effect to improve corrosion resistance of zinc and prevent hydrogen generation can not be obtained. On the other hand, if the amount is more than 1.0 pts.wt., good discharge performance can not be obtained because a barrier is formed by the alkylbenzene sodium sulphonate to prevent the dissolving reaction of zinc, etc. Thus, hydrogen gas generation in the battery is greatly suppressed and yet the battery performance is improved even if the mercury content ratio is lowered than heretofore.

Title: Rgb color monitor
Inventor: YOSHII MASAYUKI
IPC: H04N9/68
Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To prevent a white balance from changing even when a video signal is clipped with the luminance not causing defocus in the case that an RGB video signal is given with a white level (714 mV) to the RGB color monitor. SOLUTION: The RGB color monitor is provided with a reference video signal circuit 1, which connects to an RGB preamplifier 12 by switching a switch 4 in a prescribed timing. The output of the RGB preamplifier 12 to which the reference Video signal circuit 1 is connected connects to a voltage hold circuit by switching a switch 8 at the same timing as that of the switch 4 and the circuit 9 holds a peak level as a clip voltage. A clip circuit 7 clips the Video signal with the clip voltage stored differently from the RGB colors at a conventional display timing other than the timings above. Since the RGB Video input signal 15 larger than the reference Video signal is clipped at the clip voltage differently from the RGB colors, the white balance is unchanged even at the highest luminance.

Title: Application liquid for heat insulating film
Inventor: SATO ATSUSHI
IPC: H01J9/20
Filed: 1989-09-12
Abstract: PURPOSE:To prevent a metalized discharge lamp from being blackened with the percentage of residual carbon element in a heat insulating film reduced by forming application liquid, which is applied to form the heat insulating film composed of metal oxide at the end of a luminous tube, with mixed solution of water, metal oxide powder and non-polar polymeric binder. CONSTITUTION:A heat insulating film 10 is formed by applying application liquid for the heat insulating film to the end of a luminous tube 3 and burning it, and the application liquid is formed with the following elements: alumina powder with the average size of 2-3mum or so and polyethylene oxide as non- polar polymeric binder with 13wt.% or so thereto, e.g. mixed and dissolved in water. As the non-polar polymeric binder is used as organic binder of the application liquid, carbon element has no fear of being charge-coupled with metal oxide, and it is easily splashed in burning and prevented from being left in the heat insulating film. It is thus possible to reduce the percentage of such inconvenience as attachment to the inner face of the outside tube 1 which is then blackened.

Abstract: PURPOSE:To restain a slip from occurring as well as to make the constant holding of load balance between rolls, by detecting the slip in detection and comparison of peripheral velocities in each roll, and controlling the peripheral velocity so as to keep each roll load constant at the time of slip detection. CONSTITUTION:Rotation sensors 11 and 12 and peripheral velocity operators 13 and 14 are all installed in each of rolls 1 and 2 constituting a bridle device, and a peripheral velocity of each of these rolls 1 and 2 is monitored by these elements.

Patent JP-H0283484-A (JP)
Title: Doppler sensor
Inventor: KATORI AKIO
IPC: G01S13/56
Filed: 1988-09-21
Abstract: PURPOSE:To prevent erroneous operation due to noise of large amplitude by outputting a detection signal when the amplitude of a bead wave due to the mixing of a reflected wave and a transmission wave exceeds a definite time prescribed value or more. CONSTITUTION:The signal from an oscillation circuit 1 is transmitted from a transmitter 2 and the reflected wave from a moving object 3 is received by a receiver 4. The receiving signal is mixed with the signal from the oscillation circuit 1 in a mixing circuit 5 and a bead signal is taken out from a band- pass filter 7 through a preamplifier 6. This bead signal is amplified by an amplifier 8 and, in a case exceeding a prescribed value, a comparator 10 transmits a '1' signal. A circuit consisting of a differentiation circuit 13, a timer 14 and an inverter 15 receives the '1' signal to close the gate of an AND circuit 16 for a definite time. Therefore, only when the output of the comparator 10 becomes '1' for the definite time or more, the output of the AND circuit 16 is issued.
